The Honorable A. J. Eggenberger
Defense Nuclear Facilities Safety Board
625 Indiana Avenue, NW, Suite 700
Washington, DC 20004 – 2901
Dear Mr. Chairman:
On December 7, 2004, the Defense Nuclear Facilities Safety Board (Board) issued Recommendation 2004-2, Active Confinement Systems. The Department of Energy’s (DOE) Implementation Plan (IP) for Defense Nuclear Facilities Safety Board (DNFSB) Recommendation 2004-2 requires the DOE to “[r]evise, as necessary, the Ventilation System Evaluation Guidance document based on experience and lessons learned from the pilot facility evaluations.”
This deliverable (deliverable 8.6.4) has been completed using the pilot evaluations for:
· Savannah River Site Actinide Removal Process 242-96H and 512-S Facilities
· Idaho Cleanup New Waste Calcining Facility
· Savannah River Site Pit Disassembly and Conversion Facility
The pilot evaluation for PF-4 facility at TA-55 at the Los Alamos National Laboratory has been completed, but has not yet been fully reviewed by the Independent Review Panel (IRP). After discussion with the Recommendation 2004-2 IRP, National Nuclear Security Administration staff and the Board staff, it was decided to close this commitment based on the information gained from conducting three of the four pilot evaluations.
Based on these evaluations, the IRP has concluded that the Ventilation System Evaluation Guidance is fundamentally sound and that no significant revisions to it are required. Instead, an addendum to the Guidance has been prepared that contains cautions and lessons learned from the pilots (see Enclosure). This addendum will be shared on a DOE-wide basis through the IRP.
If you have questions regarding this issue, please contact me or John J. Nichols, Acting Director for the Office of Nuclear Safety and Environmental Policy at (301) 903-1018.
